	 * 			生成订单后用户可以: 取消订单  付款 
	 * 			1 ==> 待发货
	 * 			用户已付款 ==> 等待商家发货
	 * 			2 ==> 已发货
	 * 			等待用户收货  此时用户可以进行收货或者退货
	 * 			此时界面展示两种状态 一种是退货 一种是退货中  根据字段isReturn进行判断 0 退货申请 1 退货中
	 * 			3 ==> 已完成
	 * 			4 ==> 已退单
	 * 			3 和 4 的数据在一起展示
	 * 			用户收货或退货之后 订单就变成已完成的状态  此时分为两种情况
	 * 			第一种是订单已完成 
	 * 			第二种商品全部退完 状态自动变更成为已退单的状态
	 * 			5 ==> 无效订单
